title: Living related pancreas transplantation alone with enteric drainage in Japan: case report.
abstract: In this study, we report a living donor partial pancreas transplantation using intraportal donor-specific leukocyte transfusion (DSLT). The recipient was a 38-year-old woman who had type I diabetes mellitus for 17 years. Hypoglycemia occurred 2 or 3 times per week. Her hemoglobin A1c level was 9.0%, and she required 70 U of insulin almost every day. The donor was her 64-year-old father. The steroid-minimized immunosuppressive protocol included 1.5mg of thymoglobulin administered with a steroid bolus on days 0, 4, and 7 postoperatively. Steroids were never prescribed thereafter. Postoperative maintenance therapy included tacrolimus (FK506) and mycophenolate mofetil. In addition to these conventional approarches, we administered intraportal DSLT on days 0, 1, 4, and 7 after transplantation. The donor-specific leukocytes (40mL) had been separated from donor whole blood using an apheresis filter (Cellsorba EX; Asahi Kasei medical Co, Ltd, Tokyo, Japan). In the recipient operation, a segmental pancreas graft was transplanted into the right iliac cavity with enteric drainage with a pancreatic duct stent. Operation time was 6 hours. The postoperative course was uneventful. The patient was discharged on day 15 after transplantation. There was no acute rejection for six months after transplantation. The hemoglobin A1c level recovered to 5.1% with 6 U of insulin per day. At immunologic analysis, only interleukine-10 cytokine production was elevated at 7 days after transplantation. At flow cytometry cross-match analysis, the immunoglobulin M antibody decreased from day 7 after transplantation. We conclude that intraportal DSLT may be an effective adjunct to a steroid-free regimen.
